Akira Konoe is the younger brother of Moyako Konoe. In their youth, he once confided to his sister his childish wish to marry her when he grew up. This single, long-ago remark became the bedrock of his sister’s persistent conviction that he harbors improper and obsessive feelings for her.

As a teenager, he displays entirely ordinary conduct in his dealings with his sister, acting in ways typical for a boy his age and showing no sign of the perverted motives she ascribes to him. His general demeanor is unassuming, and he seems completely oblivious to the elaborate fantasies his sister constructs from their shared past.

He feels a degree of embarrassment regarding his sister’s behavior, especially when they are out in public together. While he notices her odd conduct, he usually dismisses it without deep investigation or alarm. The notion of his perversion is clearly a fiction born from his sister’s imagination, not from his own actions or desires.

His role remains steady, acting as the straight man to his sister’s comedic misinterpretations of their relationship. His background is rooted entirely in this foundational childhood event and its continuing, misunderstood influence on his sister.
